Of course the Left has dogmatized us. They have no other recourse. They can't argue their case; it's been refuted too many times and too many ways. But their politics is the foundation of something else: their self-conception as smarter and more moral than the rest of us. So they have to put it above all logical or evidentiary examination -- and the only way to do that is to ridicule or vilify anyone who dares to disagree.
